How to check if a process is running via a batch script

I've heard of batch scripts, but couldn't find any official documentation on it. Is this possible with batch scripts?

Also, can it send emails?

EDIT: Basically I need to check if a certain application is running, and send an email if it isn't as a notification. Can this be done via batch scripts?

You can use the PsList from Sysinternals to find out what is there:

and then kill it with PsKill:
